Figure 2. Stability of aminosilane-coated superparamagnetic iron oxide nanoparticles. (A) Polydispersion of the hydrodynamic diameter of the aminosilane-coated superparamagnetic iron oxide nanoparticles during a 24-hour period. (B) Values of the mean hydrodynamic diameter of the aminosilane-coated superparamagnetic iron oxide nanoparticles, with no significant difference (p>0.05).

AU: arbitrary units.
